Clinical predictors for nondiabetic kidney diseases in patients with type 2 diabetes mellitus: a retrospective study from 2017 to 2021.

Background: Nondiabetic kidney disease (NDKD), which is prevalent among patients with diabetes mellitus (DM), is considerably different from diabetic kidney disease (DKD) in terms of the pathological features, treatment strategy and prognosis. Although renal biopsy is the current gold-standard diagnostic method, it cannot be routinely performed due to a range of risks. The aim of this study was to explore the predictors for differentiating NDKD from DKD to meet the urgent medical needs of patients who cannot afford kidney biopsy.

The development of a candidate of desensitization vaccines against Der f 2 nearly without IgE-binding activity.

Considering the important role of Der f 2 in house dust mites mediating allergic diseases and allergic adverse effects during allergen-specific immunotherapy (AIT), we intend to develop a candidate of desensitization vaccines against Der f 2 without allergenicity. According to the reported immunoglobulin E (IgE)-binding B and T cell epitopes of Der f 2, four candidates of desensitization vaccines against Der f 2 were developed. Recombinant wild-type Der f 2 (rWt-Der f 2) preserved conformational and linear IgE-binding B epitopes.

Ultra-wideband surface plasmonic Y-splitter.

We present an ultra-wideband Y-splitter based on planar THz plasmonic metamaterials, which consists of a straight waveguide with composite H-shaped structure and two branch waveguides with H-shaped structure. The spoof surface plasmonic polaritons (SSPPs) supported by the straight waveguide occupy the similar dispersion relation and mode characteristic to the ones confined by the branch waveguides. Attributing to these features, the two branch waveguides can equally separate the SSPPs wave propagating along the straight plasmonic waveguide to form a 3dB power divider in an ultra-wideband frequency range.
